- Improve support for multiple domains. (In preparation for new rpc.yppasswdd.)
yp_dblookup.c:
- Improve error reporting: be more selective as to what error code
we return when a (dbp->get) fails.
In yp_server.c:
- Modify ypproc_xfr_2_svc() so that it sends both a return status and
a yppush callback (if necessary: normally ypxfr is supposed to send the
callback once it's done transfering a map, but if we can't get ypxfr
off the ground for some reason, we have to send it here instead) and
do it in the right order: have to send the reply to the ypproc_xfr
request first, then send callback. This requires us to cheat a bit:
you're supposed to just return() and let the RPC dispatcher send
the reply for you, but we wouldn't be able to send the callback message
if we did that, so we have to call svc_sendreply() ourselves, then
send the callback, and then return NULL so that the RPC dispatcher
won't call svc_sendreply() itself.
- Also modify ypproc_xfr_2_svc() so that it doesn't invoke ypxfr with
the -f flag: this overrides the order number checks, which prevents
us from ever refusing maps that aren't newer than then ones we already
have.
In yp_access.c:
- Fix a typo in the TCP_WRAPPER support code (which is #ifdef'ed out
by default): a close paren somehow vanished into the ether.
- Add a ypxfr_callback() function that we can use to signal failure to
yppush(8) in the event that we can't fork()/exec() ypxfr(8). yppush
only checks the return status from YPPROC_XFR enough to determine
that the RPC succeded: it relies on its callback service to figure
out whether or not the transfer actually worked.
- Give yp_dblookup.c its own debug variable (ypdb_debug) so that DB
access debugging messages can be turned on or off independent of the
program's global debug messages.
- Have the Makefile rpcgen the ypushresp_xfr_1() client stub for us and
nuke the unneeded rule for yp_xdr.c that I left in by mistake (the XDR
filters live in libc now).
equivalent to the old ypserv, except that it doesn't support the
-p [port] option to force the server to use a particular port.
The server stubs and yp.h header file are auto-generated from the yp.x
protocol definition file. The auto-generated XDR routines in libc/yp
are also used. The database access code has been broken out into a
seperate module so that other NIS utilities (ypxfr in particular)
can use it.
Note that the old mknetid script is being temporarily moved here; it
will be replaced by an mknetid program which will eventually have
a home under /usr/src/libexec. (The existing script is actually
somewhat broken -- it doesn't handle hosts -- but this isn't a big
deal at this point since the netid.byname map is really only useful
fopr Secure RPC, which we don't have yet.)
